We know the cuckoo for its song and think of it as the harbinger of spring. But we also know it as a rascally bird that abandons its young to the care of unwitting foster parents. Such a double life has ensured that the cuckoo has had a substantial place in the culture of all the countries across Europe and Asia where it comes to breed. In addition, observers, natural historians and scientists have long puzzled over the bird's secretive behaviour and habits - how do they do what they do, where do they go when they are not here, why are we losing them in England? Brett Westwood in the company of various field workers who have spent lifetimes trying to figure out cuckoos explores the rich and tangled life of the bird. With Nick Davies, Jenny York, Mark Cocker, and Chris Hewson and readings by Anton Lesser and a gone-cuckoo song by Hanna Tuulikki. Producer: Tim Dee Show less
